摘　　要：火炮是一个多场耦合复杂系统,其发射过程具有高瞬态和强冲击特征,火炮振动是影响射击精度的重要因素之一,是火炮领域的重要研究内容。近年来提出了火炮多体系统动力学、非线性动态有限元、多目标多学科优化及不确定性等火炮现代设计理论与方法,对炮身、架体、底盘等重要部件及各部件间连接关系组成的火炮系统进行建模、仿真及优化,从而达到减小炮口振动、提高射击稳定性和射击安全性的目的。笔者从火炮振动与系统优化、弹炮耦合、火炮不确定性分析与优化等方面对近年来取得的成果进行了总结和分类讨论,并提出了火炮振动领域存在的问题及火炮振动与控制的应用前景。The gun is a multi-field coupling complex system,and its launching process has the characteristics of transient and strong impact.The gun vibration takes important effect on firing accuracy,and therefore it becomes the focus of the study of artillery engineering.In recent years,modern artillery design theories and methods such as gun multi-body system dynamics,nonlinear dynamic finite element,multi-objective and multidisciplinary optimization and uncertainty have been proposed to model,simulate and optimize the gun system composed of significant components,e.g.the recoil parts,carriages,chassis and the connection relationship between components,so as to reduce muzzle vibration,improve shooting stability and shooting safety.This paper summarizes and discusses the achievements in gun vibration and system optimization,projectile-barrel coupling,gun uncertainty analysis and optimization.Finally,the problems existing in the field of gun vibration and the application prospect of gun vibration and control are put forward.
